Reconstruction of lateral nasal tip and medial alar defects is challenging. Contour, symmetry, and skin texture of the nose, along with adequate nasal airway patency, should be preserved. The Z-advancement flap is a novel reconstruction technique designed for optimal cosmesis and function.
To evaluate the aesthetic and functional outcomes of Z-advancement flap nasal reconstruction.
Twenty-nine consecutive patients with defects 1 cm or less in diameter on the lateral nasal tip or medial ala underwent Z-advancement flap repair. Patients completed a survey assessing cosmesis and airway patency. Three physicians evaluated standardized photographs on visibility of scar lines, erythema and telangiectasia, and contour and symmetry of the ala and nostril opening.
Twenty-eight (96%) patients completed survey questionnaires. All patients were satisfied with the look and feel of their reconstructed nose. Twenty-four (86%) saw no visible scar or abnormality. Postoperative photographs were available for review in 19 (66%) patients. In 95% to 96% of physician ratings, scars were invisible or visible only on close inspection, and alar symmetry was unchanged or only slightly altered. In 88%, nostril opening symmetry was unchanged or slightly altered.
The Z-advancement flap preserves aesthetic subunits of the nose to produce excellent cosmesis and patient satisfaction for defects of the lateral nasal tip or medial ala 1 cm or less in diameter.
外侧鼻尖和鼻翼内侧缺损的重建具有挑战性。应保持鼻子的轮廓、对称性和皮肤质地,以及足够的鼻腔气道通畅。Z 成形瓣是一种新颖的重建技术,旨在实现最佳的美容和功能效果。
评估 Z 成形瓣鼻重建的美学和功能效果。
29 例连续患者的外侧鼻尖或鼻翼内侧有直径不超过 1cm 的缺损,行 Z 成形瓣修复。患者完成了一项评估美容和气道通畅性的调查。3 名医生评估了标准化照片上的疤痕线可见度、红斑和毛细血管扩张、鼻翼和鼻孔开口的轮廓和对称性。
28 例(96%)患者完成了调查问卷。所有患者对重建后的鼻子外观和触感都感到满意。24 例(86%)患者看不到可见的疤痕或异常。19 例(66%)患者有术后照片可供审查。在 95%至 96%的医生评分中,疤痕肉眼不可见或仅在近距离观察时可见,鼻翼对称性无变化或仅略有改变。在 88%的情况下,鼻孔开口对称性无变化或仅略有改变。
Z 成形瓣保留了鼻子的美学亚单位,为直径不超过 1cm 的外侧鼻尖或鼻翼内侧缺损提供了极好的美容效果和患者满意度。
